i've been curious about the coast guard for some time and finally read the wikipedia page on it this morning. i see that it's a service that is definitely needed, and i think it's cool that the US has the best coast guard in the world, but i'm just curious about the main reasons people choose to go coast guard instead of the u.s. navy. is it a "defend the homeland closer to the homeland" thing? or the law enforcement aspect? or the styling new boats: http://www.defenseindustrydaily.com/images/SHIP_USCG_NSC_Concept_lg.jpg or something else?
